Inductive-capacitive coupling amplifier.Resistive-capacitive coupling amplifier.There are different types of methods in the interstage coupling amplifier. This type of amplifier is classified by using the coupling method of the signal at the input, output and between the stages. The voltage follower is called as non-inverting amplifier and it has unity gain. The non-inverting amplifier continuous the phase of the input signal waveforms and the emitter is a non-inverting amplifier. The common collector circuit is called as an emitter follower, source follower, and cathode follower. The input signal is in between collector and emitter is inverted it is relative to the input. The common emitter is the most frequently to provide amplification of a voltage applied between base and emitter. In the case of Field Effect Transistor, it has the corresponding configurations like common source, common gate, and a common drain. a common emitter, common base, and common collector. In the Bipolar Junction Transistor, there are three classes namely. The classification of the amplifier is based on the device terminal which is common to both input and output circuit. There are four types of amplifiers and which are dependent on the source used as a linear analysis. It may be current or voltage can be used in the input or either in the output. The electronic amplifier uses only one variable i.e. The classification of amplifiers is shown in the following Nowadays, most of the amplifiers used in the market are transistors but, vacuum tubes are also using in some of the applications. There are different types of amplifiers includes a current amplifier, a voltage amplifier or the transconductance amplifier and trans-resistance amplifier. The last one is current quality and voltage are being amplified The next one is the audio amplifier and amplifies the signal in the range of less than the 20 kHz and the RF amplifier amplifies the radio frequency ranges from 20 kHz to 300 KHz. The first one is by the frequency of the electronic signal being improved. The amplifiers can be categorized in different types. AmplifierĪn amplifier is used in all the electronic equipments. The amplifier is also a discrete part of the electrical circuit which is continued with the other device. The amplifier is quite opposite to an attenuator if the amplifier provides the gain, hence the attenuator provides the loss. An amplifier modulates the out of the power supply is based on the properties of the input signal. The function of the amplifier is by using the power from the power supply and longer altitude, it controls the output signal with the help of input signal. The amplifier is an electronic device used to increase the signal of current, voltage and power.
Simply the amplifiers are called as an amp. What is an Amplifier and Classification of Amplifiers?
